1. This specification describes the basic performance, technical requirement, testing method, warning and caution of the Li- ion Cylindrical rechargeable battery .The specification only applies to PAC Technology Co.,Ltd.
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.
2.0.2C capacity testing of 12v 18650 lithium battery pack
After standard charging, rest battery for 10min, then discharging at 0.2C to voltage 3.0V, recording the discharging time.
3. Cycle life testing of 12v 3.5Ah lithium battery pack
Constant current 0.5C charge to 4.2V, then constant voltage charge to current declines to 0.01C, rest 10min,constant current 0.5C discharge to 3.0V, rest 10min. Repeat above steps till continuously discharging capacity Higher than 80% of the Initial Capacities of the Cells.
